自适应交互式马尔可夫链蒙特卡罗算法的收敛性

Convergence of adaptive and interacting Markov chain Monte Carlo algorithms

G. Fort, E. Moulines, P. Priouret

摘要:

自适应交互式马尔可夫链蒙特卡罗算法(MCMC)是近年来提出的一种新算法。这些新颖的模拟算法旨在提高对复杂分布进行采样的模拟效率。最近推出的一些算法(如自适应Metropolis算法和交互回火算法)的动机,我们开发了一个通用的方法和理论框架,建立既收敛的边缘分布和强大数律。该框架削弱了Roberts和Rosenthal在开创性论文中引入的条件[J. Appl. Probab. 44(2007)458- 475]。它还涵盖了使用马尔可夫转移核对目标分布$π$进行采样的情况,该马尔可夫转移核具有不同于$π$的平稳分布。

英文摘要:

Adaptive and interacting Markov chain Monte Carlo algorithms (MCMC) have been recently introduced in the literature. These novel simulation algorithms are designed to increase the simulation efficiency to sample complex distributions. Motivated by some recently introduced algorithms (such as the adaptive Metropolis algorithm and the interacting tempering algorithm), we develop a general methodological and theoretical framework to establish both the convergence of the marginal distribution and a strong law of large numbers. This framework weakens the conditions introduced in the pioneering paper by Roberts and Rosenthal [J. Appl. Probab. 44 (2007) 458--475]. It also covers the case when the target distribution $π$ is sampled by using Markov transition kernels with a stationary distribution that differs from $π$.
